Abstract

A pneumatic radial tire having a belt layer comprising a steel cord is disclosed. The steel cord is constructed as follows: (a) a 1+N structure is provided, where sheath filaments amounting to N in number are stranded up around a spirally-reformed core filament in a cord longitudinal direction; (b) a shape of a cord cross section is flat; (c) an open structure is provided, where a gap is formed between adjacent filaments of the sheath filaments in the cord cross section; (d) the core filament is caused to bite between the adjacent filaments; (e) a spiral direction of the core filament is identical to a stranding direction of the sheath filaments; and (f) a major axial direction of a flat surface of the cord cross section is set along a facial direction of the belt layer.
